Abstract

In an apparatus for processing moist dust and mud from dust removal equipment, especially in the steel industry, wherein the mud is concentrated, fractionated and dewatered in several steps the mud is dewatered in a centrifugal separator, to allow the mud from the dust removal equipment of blast furnaces and steel works to be dewatered in an environmentally acceptable and simple and cost effective way.
